SPECIFICATION forming part of Letters Patent N0. 545,278, dated August27, 1895.

Application filed April 15, 1895! Serial No. 545,747- (No model.)

To all whom it may concern:

Be it known that l, HERMANN O. FISCHER, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Buttons; and'l dodeclare the following to be a full, clear, and exact description of theinvention, suchas will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to buttons, and has for its object an improvementin that class of articles known as separable buttons, facilitating theirinsertion through and withdrawal from the buttonholes and providingbutton together.

In the accompanying drawings, wherein like letters represent like partsthroughout, Figure -1 shows a side view of the detentshank andface-plate. Fig. 2 shows an end view from the shank side of theface-plate. Fig. 3 shows a side view of the same parts turnedone-quarter revolution from the position of the first figure. Fig. 4;shows a section of the receiving member along the slots in itscylindrical projection. Fig. 5 shows an end view of the receiving memberfrom the cylinder side. Fig. 6 shows a section of the receiving memberupon a plane at right angles with that of the section shown in thefourth figure. Fig. 7 shows a side view of the two members, partly insection, when locked together. Fig. 8 shows a side view of a medification of the shank to receive a jewel upon one end, the otherextremity being provided with a screw-thread. Fig. 9 shows alongitudinal section of the receiving member for the modification, andFig. 10 an end view of the ninth figure.

Considering the first figure, the face-plate B has projecting from itssurface centrally the shank A, provided with base-lugs a a and end lugsa a, arranged in pairs, terminating diameters of the shank A at rightangles to each other.

From an inspection of Fig. 3 the inclination given to the sides of thebase-lugs a o toward the outer end of the shank A may be seen. The saidinclination of the lugs also appears in Fig. 8.

Referring to Fig. 4, it will be seen that the receiving member of mynewly-invented button consists particularly of a split cylindricalportion D, firmly attached to a plate 0 at one end. The cuts in thecylinder D consist of lengthwise slots d, the full cross area of whichis carried through the plate 0. The letter E represents merely the onter covering and finish of the plate 0. The parts are assembled for useby passing the slotted cylinder D through the buttonhole and insertingthe shank in such manner that the end lugs ad occupy and can travel inthe slots d d. It will be observed in Figs. 3 and 8, as previouslystated, that the base-lugs a a present an inclined side toward the endof the shank, and when the sides of the cylinder D meet the lugs a a theformer, being flexible, rise upon the latter, yielding to slight inwardpressures upon the faces B and E. From the position of the parts thusresulting, the end lugs o a being now beyond the plate 0, a quarter-turngiven the shank A brings the base-lugs a a into the slots d d, allowingthe elastic divisions of the cylinder D to resume their normal conditionof no stress. The parts are in this manner locked together, and theirrelease obviously follows areversal of the movements described.

Figs. 8, 9, and 10 show the end of the shank A threaded, as at F, and abore with a corresponding thread through the plate 0, and in thismodification the slots d (1 do not necessarily continue through theplate. The baselugs a a are retained upon the shank, and theconstruction of the device, as well as the mode of operating it, issubstantially the same as set out above in this description.

\Vhat I claim, and desire to protect by Letters Patent, is thefollowing:

1. In a separable button, the member hear ing a-shank provided near itsbase with lugs at opposite points, the other end of the said shank beingsuitably constructed to engage corresponding devices. within thereceiving member, the receiving member consisting of a hollow cylinderor sleeve, slotted lengthwise, fixed at one end to a plate, the portionsof the said cylinder included between the said slots possessingelasticity, the said plate being pierced by an orifice corresponding tothe bore of the cylinder and suitably constructed to engage the outerend of the said shank substantially as and for the purposes shown anddescribed.

2. In a separable button, the member bearing a shank provided with lugsat opposite points near the base and at opposite points near the freeend of the said shank, the line joining the middle points of oppositelugs lying in different planes, the receiving member consisting of ahollow cylinder or sleeve, slotted lengthwise, fixed at one end to aplate, the
